WWW::Scripter::History - History object for WWW::Scripter
  - length
- Returns the number of items in the browser's history.
    This is 1 when you haven't gone anywhere yet. 
- index
- Returns the current position in the history list.
- go ( $distance )
- Moves forward (positive $distance) or back
      (negative) in history, or reloads the page if
      $distance is 0. If the
      $distance would cause navigation beyond either
      beginning or end of the history list, nothing happens.
- back
- Same as "$history->go(-1)".
- forward
- Same as "$history->go(1)".
- pushState(
    $some_scalar, $title, $url )
- This adds a 'dummy' entry to browser history, which is identical to the
      current page (actually, it is the current page), except that it has
      the state information contained in $some_scalar
      associated with it. The $url, if specified,
      becomes the URL of the current page (so a script can lie about what the
      URL is). The $title is ignored.
